my rant on fw sharks

[X24]

An LFS near me makes up names as they go.

most of the sharks i.e. RTB shark, rainbow, albino, are named for their resemblance, not for the links in family to true sharks

there actually is a species of true freshwater sharks in australia that is very rare(known from about 5 speciemens) that is related to the bull shark.

sounds like the long way to say bull shark that enters fresh once in a while.
lol

Did none of you read Dr. Joes response, there are freshwater sharks.

 

[guppy]

all true sharks live in sw

This is not actually true.
As mentioned in this thread the lake nicaragua shark (a sub-species of the bull shark) is a land locked population that live and breeds in freshwater, there are also at least three species of speartoothed (riversharks)sharks that have only been found in freshwater. These are all in the genus Glyphis. Supposedly there are actually 6 species but only three are currently accepted as established. One of them is known from only a single specimin found in New Guinea.

Some sharks migrate into the freshwater habitat of Brisbane's harbour for some months of the year. I believe they are bullsharks. We also get dolphins.
Another reason why rainbows, RTB, Bala 'sharks' etc are called that is due to just a name. A 'shark' name sounds much more appealing then Bala Cyprinid. Also, many are named 'shark' due to thier high dorsal and torpeado shaped body. Along with 'sharky' fins.
My 3 Bala's act so very skittish, and my 4" Red Tail Black patrols the tank as if a Great White is hunting for prey.

bull sharks can live in freshwater and are a true shark

I do love my black "shark" he doesnt look much like a shark, or act much like one but whatever the hell some common name he has...hes a great fish. As are most of our other tropical home kept "sharks". I think the LFS i bought my suncat fish was trying to call it a shark but I cant remember for the life of me what exactly they were calling it
